C. J. ROONEY AND D. RE-NSHAV, OF NEW YORK, N. Y.

SPRING-HINGE.

Specification of Letters Patent No. 25,585, dated September 27, 1859.

r 'o all whom it may concern:

Be it known that we, CORNELIUS J. RooNEY and DAVID RENSHAW, both of NewYork, in the county of New York and State of New York, have invented anImprovement in Spring Door-Hinges, the construction and operation ofwhich we have described in the following specification and illustratedin its accompanying drawings with sufficient clearness to enablecompetent and skilful workmen in the arts to which it pertains or ismost nearly allied to make and use our invention.

Our said invention consists in the manner hereinafter described ofcombining and arranging' the spring and the parts of the hinge inconnection with each other, by which the removal and replacement of abroken spring without interfering with the connection of the parts ofthe hinge or its attachment to the door is Jfacilitated, and the hingemade much more convenient to use and to graduate, as more fullydescribed below.

The accompanying drawings illustrate our invention as follows Figure lis an elevation of the inside of the hinge when opened. Fig. 2 is a backelevation of the hinge when closed. Fig. 3 is a side elevation. Fig. 4is a plan of the hinge when closed. Fig. 5 is a -section through theline XX on Figs. l, 2, and 3, showing the manner in which the spindle orshaft is connected to one of the parts of the hinge.

A and B are the sides or wings of the hinge. C is the spindle or aXis bywhich they are connected. The upper part of the sides is cut away aroundthe axis as shown, to receive the spring E, the inner end of which iitsby an abrupt turn into a groove f in the side of an enlarged portion ofthe' spindle, and the other or outer end of it is fastened to the leaf Aby means of screws e, e. The spindle c, .where it fits into the upperremaining section of the joint, is made square, and this upper sectionof the joint, being part of the wing B, and having a square socket toreceive the shaft, furnishes the other terminus or extremity of theattachment of the spring, by which the necessary resistance to the actof opening the hinge is attained. It will be observed that by thisarrangement the shaft of the hinge may be so turned as to bring the slotf upon any side of it with reference to the other parts of the hinge, bywhich the force of the spring upon the hinge may be varied to suit theservice it is intended to perform. The arrangement of parts describedalso furnishes the means of removing a broken spring without taking thehinge apart or disturbing its attachment to the door upon which it isplaced, or its attachment to the jamb or easement. To do this, the dooris opened, the screws c, e, drawn, and the pieces of the broken springremoved, which is done without trouble; the new spring is then coiledsufficiently close to allow it to be introduced so as to bring its endsin proper position; and having then been slid into place upon the shaftso as to properly enterl its inner end into the groove intended for itsreception, the outer end is brought into place upon the leaf A, andsecured by the screws c, e, as represented on the drawings. Should thespring be found upon trial to give with the adjustment it has received,either too much or too little force, its action may be modified byraising the shaft C till its square part is above the socket in theupper section of the joint, and turning said shaft so as to bring theslotted or grooved side upon any side relatively to the other parts thatwill give the required adjustment.

Ve are aware that a spring has been combined with a door hinge before,and this we do not claim as our invention; but in all the cases of suchcombination with which we are acquainted the parts are not so combinedas to allow the facilities of removal and adjustment which it is thepurpose and result of our invention to give.

The particular improvement which we claim as constituting our saidinvention is- The arrangement of the coiled spring E, shaft C, and wingsA and B, in combination with each other as described for the purposesstated, when the parts are constructed substantially as herein setforth.
